CLOSURE FOR CANS, 80C.

SPECIFICATION forming part of Letters Patent No. 532,990, dated January 22, 189 5. Application tiled November 22, 1893. SerialN'c. 491,674. (No model.)

To all whom it may concern:

Be it known that I, JOHN RAU, a citizen of the United States, residing at Chicago, in the i county of Cook and State of Illinois, have invented certain new and useful Improvements in Closures for Cans and other Vessels, of which the following is a specification.

'The present invention relates to that class of closures which are so incorporated with the discharge spout or nozzle of the vessel that said spout or nozzle serves as a handle for operating the closure, and in whichvthe closure is ofsuch a nature that the vessel re'- qnires but one opening through which it may be filled and emptied, and in which opening the associated parts going to make up the closure and spout are arranged.

The invention consists in certain features of novelty that are particularly pointed out in the claims hereinafter, and in order that it may be fully understood I will describe it with reference to the accompanying drawings, which are made a part hereof, and in which- Figure l is a side elevation of a vessel with the improved closure applied thereto. Fig. 2 is a plan view thereof. Fig. 3 is an axial section of the improved closure on a larger scale.

A represents the vessel, which may be of any desired construction, material and shape. It is provided with a single opening in which is placed and secured a tube B which projects some distance into the interior of the vessel. The tube is provided at its outer end with a flange resulting in a shoulder b, and within the vessel it is provided in its side with an opening b. Fitting within this tube is a second tube C provided with an opening vc, so located that by a rotary movement of one tube within the other the openings b and c may be brought to register with each other and permit liquid to flow either inward or outward through said openings, and in order to prevent liquid from either entering orleaving thevessel through any other passage,'the inner end of either one or both of the tubes is closed. As shown in the drawings it is the inner tube, but this is merely illustrative, and the invention in its broadest aspect is not limited thereto. The outer end of the inner tube is left open, and is preferably provided `as it is discharged.

with a lip C for directing the flow of liquid Secured to the tube C is a linger D which engages the shoulder b of the tube B and prevents the relative endwise movement of the tubes, while permitting their relative rotary movement. A suitable stop is also provided for limiting this relative rotary movement and preventing farther movement as soon as 6o the tubes have reached such relative positions that the openings b and c register. As shown in the drawings, this stop consists of a pin E carried by the tubeC and adapted to come in contact with the shoulders e formed on the tube B by cutting away a portion of the top side of its iange. In order to compensate for wear, resulting from they frictional contact of the meeting surfaces of the two tubes,'they are preferably tapered slightly, as 7o shown in the drawings.

It will be understood that vin order to either till or empty a vessel provided with a closure as above described, the tube C is turned until the openings b and c register, and that when the contents of the vessel is to be protected from contact with the atmosphere the parts are placed as shown in Fig. 3 of the drawings, in which positions each tube closes effectually the opening through the other.

What I claim as new, and desire to secure by Letters Patent, is-

l. The combination with a vessel, of a tube secured in an opening in the vessel, said tube extending into the vessel, and another tube 8 5 open at its outer end and rotatively mounted within the first tube, one of said tubes being closed at the inner end, and both of said tubes within the vessel being provided with openings adapted to be brought to register with 9o each other by a rotary movement of the innertube, and a finger, or its equivalent, outside of the vessel on one of the tubes in constant engagement with a flange on the outside of the other tube to prevent lateral movement, said finger being removable whereby the inner tube maybe removed from the outer tube from the outside of the vessel, substantially as set forth.

2. The combination with a vessel, of a tube roo secured in an opening in the vessel, said tube. extending into the vessel, and another tube open at its outer end and rotatively mounted within the first tube, one of said tubes being closed at the inner end, and both of said tubes Within the vessel being provided with open- 5 ings adapted to be brought to register with each other by a rotary movement of the inner tube, apin on one of the tubes adapted to engage with shoulders on the other tube for limi iting the rotary movement of the inner tube, 1o and a finger, orits equivalent, outside of the Y vessel on one of the tubes in constant engagement with a iiange on the outside of the other tube to prevent lateral movement, said finger being removable whereby the inner tube may x5 be removed from the outer tube from the outside of the vessel, substantially as set forth.

3. The combination With a vessel having an opening, of the tube B secured in said opening and projecting into the vessel, the tube zo C fitting Within the tube B and capable of movement relatively thereto, one of said tubes being closed at its inner end and both being provided with openings which are adapted to be brought to`1egister with each other by a 25 movement of the innertube, a shoulderformed on one of said tubes, and a fin ger carried by the other and engaging said' shoulder for preventing the withdrawal of the inner tube, said inner tube being left open at its outer end 4for the discharge of the contents of the ves- 3o sel, substantially as set forth.

4:.v The combination of a vessel having an opening, the tapering tube B secured in said opening and having a shoulder b and the opening b', the latter located within the ves- 3 5 sel, the tapering tube C having opening c fitting Within the tube B and left open at its outer end for the discharge of the contents of the vessel, the finger D carried by the tube C and engaging the shoulder b, the pin E car- 4o ried by the tube G,.and shoulders on the tube B for engaging the pin E and limiting the relative rotary movement of the tubes, the inner end of one of the Y tubes being closed, substantially as set forth.
